BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 674,502, dated May 21, 1901.

Application led August 29, 1898. Renewed October 26, 1900. Serial No. 34,471. (No model.)

To n/,ZZ whom, t muy concern:

Be it known that I, SAMUAL M. GOLDBERG, a citizen of the United States, and a resident of Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bottle-Stoppers, of which the following is a specification. y

This invention relates to astopper device which is arranged in the neck of a bottle, demijohn, jug, or other similar vessel after the same has been lled for the purposeof preventing the refilling of such vessel after the original contents have been removed therefrom.

The object of my invention is the production of a simple, cheap, and thoroughly-reliable device for this purpose.

In the accompanying drawings, Figure 1 is a sectional elevation of the neck of a bottle provided with my improved stopper device. Fig. 2 is an elevation of the stopper device viewed from that side on which the vent-pas sage is arranged. Figs. 3 and 4 are vertical cross-sections in lines 3 3 and 4 4, Fig. 1, respectively. Fig. 5 is a top plan View of the stopper device. Figs. 6, 7, and 8 are hori Zontal cross-sections in lines 6 6, 7 7, and 8 8, Fig. l, respectively. Fig. 9 is a detached vertical section of the stopper device, showing the parts in the position which they assume when the neck of the bottle is inverted in an attempt to refill the bottle. Fig. 10 is a detached vertical section of the stopper device, showing the saine in the position which it assumes when pouring the liquid from the bottle.

Like letters of reference refer to like parts in the several iigures.

A represents the neck of the bottle, which may be of any suitable form and dimensions.

B B represent the two semicylindrical parts or halves of the body of the stopper device, forming together a cylindrical or approximately cylindrical plug, which is seated in the neck of the bottle at such a distance from the end thereof that an ordinary cork or stopper can be inserted above this stopper device. The outer surface of this body is preferably slightly taperinginward ly, and the internal surface of the neck is correspondingly shaped, so that the body will seat itself tightly in the neck. The two semicylindrical partsA are tted snugly against each other with their flat diametrical sides and are secured in the neck by any suitable means-for instance, a suitable automatic fastening which locks this two-part body in the neck when it has reached the proper position. This locking device is preferably a split annular spring b, which is seated in a circumferential groove b in the two-part body and which expands into an annular groove c, formed in the inner surface of the neck of the bottle, the groove in the neck being of less depth than the thicknesses of the split spring, so that the latter projects into the groove of the two-part body when it has engaged in the groove in the neck.

The contiguous flat sides of the two parts B of the stopper-body are provided with depressions, forming the channel or passage through which the1 liquid flows in being poured from the bottle. This channel or passage has at its lower or inner end a Valve-seat e, which opens upwardly or outwardly into a valve-chamber E, having at its upper or outer end another valve-seat f, which opens downwardly or inwardly, so that both of these valve-seats open into the valve-chamber E. These valve-seats are rings which are formed Separate from the two-part body, and each is seated in two semicircular grooves or recesses, oneof which is formedin each part of the body. These valve-seats bridge the joint between the two parts of the body and so register the two parts with reference to each other, While each seat presents acontinuous or unbroken surface to the valve. From the outer valveseat f the flow-passage continues and is composed of an ascending curved portion g, a descending vertical portion H, a horizontal portion I, leading to one side of the stopperbody, and an exit ,opening upwardly through the end of this body, on one side thereof. The valve-chamber is constructed with a pocket or recess J, which is located on the same side of the body ou which the eXit i is arranged, so that this exit and the recess J are on the lower side of the stopper-body in the position in which the bottle is held in pouring the liquid from the same, as shown IOO in Fig. 10. The outer valve-seat fis arranged on the opposite side of the body.

K represents a ball-valve which is arranged in the valve-chamber E and which can seat itself on either valve-seat.

L represents a locking-pawl which isarranged in the pocket or recess of the valvechamber and pivoted at its lower or inner end to the body, while its outer end is free to interlock with the ball-valve. The pawl is preferably pivoted by means of pivot-lugs Z, formed at the inner end of the pawl and engaging in recesses formed in the contiguous inner faces of the two parts of the body. This pawl is made of such length and shape that when the bottle is inverted, so that the ball-valve seatsitself against the outer valveseat f, the pawl will bear with its free end or head Z' against the valve and will lock the same against that seat, as shown in Fig. 9. The pawl then prevents the valve from being raised from this seat either by pressure or suction, so that no liquid can be introduced into the bottle in that position of the parts.

When it is desired to pour liquid from the bottle, the neck of the latter is placed in such a position that the exit t' of the stopper device is on the lower side of the neck and stopper, as shown in Fig. l0. In this position of the stopper device the pawl is below the ballvalve, and the latter rests on the free end of the pawl and leaves an unobstructed pouringpassage from the inner valve-seat down to the exit t. The bottle can be placed almost in an inverted vertical position without causing the ball-valve to seat itself on the outer valve-seat, and the bottle can therefore be completely emptied without diiiiculty. In order to reduce the contraction of the flowpassage by the valve in this position of the parts as much as possible, the front side of the pawl, on which the valve rests, is provided in rear of the head or free end of the pawl with a depression or concavity Z2, in which the valve rests when the parts are in this position. When the neck and stopper device are inverted, so as to bring the exit il on the upper side of the stopper device in attempting to introduce liquid into the exit for refilling the bottle, the pawl is above the ballvalve, the latter seats itself against the outer seat f, and the pawl drops by gravity against the valve, as shown in Fig. 9, and so locks the valve against this seat and prevents the valve from being raised therefrom. Upon turning the bottle, so that the exit/i is again on the under side of the stopper device, the pawl is .again below the valve and drops by gravity from the valve and releases the latter.

The stopper-body is preferably provided with a vent passage, which is preferably formed, as shown in Figs. l, 2, and 5, so as to extend from the upper or outer end of the body to the base of the curved ascending portion g of the liquid-passage. In order to prevent tampering with the valve through this passage by a wire or other instrument, this passage is bifurcated or composed of a cen tral lower portion o, which opens inwardly into the dow-passage, two grooves o', which extend horizontally in opposite directions from the outer end of said lower portion 0, and two upright grooves 02, which extend from the outer ends of said horizontal groove upwardly to the upper end of the body.

The vertical portion H of the flow-passage extends above the upper end of the curved portion g and the horizontal portion I extends rearwardly beyond the lower end of the vertical portion H, forming a pocket at each bend or corner of the iiow-passage, which, in connection with the curved or oblique arrangement of the ascending portion g, practically prevent the introduction of a iiexible tube through the fluid-passage of the stopper-body into the bottle in an attempt to refill the bottle.

The several parts of the stopper device are preferably made of glass or porcelain. If desired, the mouth of the bottle may be provided with a pouring-lip of well-known construction, in which case the exit 1l of the stopper device is arranged in line with such lip.

I claim as my inventionl. The combination with a stopper-body having its liquid-passage provided with a valve-chamber which has at its upper or outer end a downwardly or inwardly opening valveseat, of a valve arranged in said chamber, and a locking-pawl arranged in said chamber below said valve-seat and pivoted at its lower end, while its upper end is free to swing against the valve and lock the same against said seat when the stopper device is inverted and the valve has seated itself against said seat, substantially as set forth.

2. The combination with a stopper-body having its liquid-passage provided with a valve-chamber which has at its upper or outer end a downwardly or inwardly opening valveseat and at its lower or inner end an upwardly or outwardly opening valve-seat, of a valve arranged in said chamber and adapted to seat itself against either seat, and a locking-pawl arranged in said chamber at one side thereof and between said seats and pivoted at its lower end near said inner seat, while the upper end of said pawl is free to swing against the valve and lock the same against said outer seat when the stopper device is inverted and the valve has seated itself against said outer seat, substantially as set forth.

3. The combination with a stopper-body having in its lower portion a valve-chamber provided at its lower end with an upwardlyopening valve-seat and at itsupper end with a downwardly-opening valve-seat and with a recess on one side of said upper valveseat, and having its liquid-passage extending from said upper valve-seat upwardly, downwardly and laterally to an upwardly-opening exit whichA is arranged on the same side as the recess of the valve-chamber, of a ballvalve, and a locking device for said valve ar- IOO IIO

ranged in said recess of the valve-chamber, substantially as set forth.

4. The combination with the stopper-body having its liquid-passage provided with a valve-chamber which has at its upper end a downwardly or inwardly opening valve-seat, of a ball-Valve arranged in said chamber, and a looking-pawl also arranged in said chamber and provided on its front side and in`1'ear of its head or free end with a depression or oonoavity adapted to receive the valve, substantially as set forth.

5. The combination with the stopper-body having its liquid-passage constructed with a valve-chamber provided at its upper or outer end with a downwardly or inwardly opening valve-seat and having its liquid-passage ex- SAMUAL M. GOLDBERG.
